This invention relates to clutches and has for its object the production of a clutch in which two split rings are disposed in a recess in one member with separating mechanism between the rings adapted tobe actuated by means carried by the other member, whereby a the split rings will be forced into frictional1 contact with the cylindrical walls of said recess thereby locking the two members to- 19 gether. r i r a a This object is attained by the mechanism illustrated in theaccompanying drawings.

For the purpose of illustrating the inven. tion, one preferred form thereof is illustrated 15 in'the drawings, this form having been found to give satisfactory and reliable results, al-. though it is to be understood that the various instrumentalities of which the invention con sists can bevariously arranged and "organ ized, and the invention isnot limited to the precise arrangement and organization of these instrumentaliti'es as herein shown and described except as required by the scope of I; the appended claims.

In the drawings, 10 is a revoluble shaft sur- I rounded by a tubular member 11 secured thereto by means ofa key 12.

From one end of this revoluble member 11 extends an annular flange 13 having at its extreme outer endfanannular lip lfl. I 7

Surrounding the tubular member 11 is a drum -15 having an annular extension 16 fitted over the periphery ofthe flange-13 and i having its outer end abutting the annular lip "This drum 15 has extending therefrom a plurality of studs 17 adapted to. be inserted into openings 18 in a pulley '19 or similar member to be driven, said pulley being indi cated by dotted lines in Fig. 1. a I

The tubular member 11 has a collar-20 mounted thereon provided with a screw 21 having a reduced shank 22 inserted into a radial hole 23 in said tubular member; i

This collar 20' abuts the outer end of the pulley 19 and retains it in position on the tubular member 11. a

The drum 15 has an annular recess 24 in one face thereof and in this recess are loose- 1y disposed an outer split ring 25 and an inner split ring 26; a a r Between the ends ofthe split rings 25 and 26 and positioned in the recess 24 is a- U- shaped block 27 secured to the flange, '13 by means of screws 28.

Within the block 27 is disposed a cam member 29 having a shank 30 extending through one wall of said block and the flange Diametrically opposite the cam '29 is disposed a similar'cam 31 having a shank 32 extending through the flange 13; The shanks 30 and 32 respectively have threaded thereto the levers 33,34.

These'levers are retainedin adjusted position upon the shanks 3Q, 31 by clamp nuts 35. The free ends of the levers 33, 34 have en larged portions 36 adapted to bear'upon the cone member 37 movable endwise of the shaft This cone member 37 is provided with an annular groove 38 with which any well known shifting device may coac t to 'move said cone 37 endwise of the shaft 10.

The outward movement of the cone member 37'is limited by the collar 39 surrounding the shaft 10 and secured thereto by the set screw 40.

The inner end of this set screw extends into an elongated depression 41 formed in the shaft 10, so that said collar may be adjusted lengthwise of said shaft 10 and'locked in its adjusted position by the set screw 40.

Disposed within the U-shaped block 27 are two pushing members 42 and 43, said pushing members having notches 44 therein in which is disposed the cam member 29.

The cam member 31 is similarly disposed in notches 45 in the pushing members 46 and 46%. f I

Each cam member 29 and 31 ispreferably diamond-shaped as indicated in Fig. 5 of the drawings, and oppositely disposed. faces thereof are normally in contact with inclined walls of the notches 44, 45.

I It is. obvious, therefore, that as soon as the cams 29, 3l are rotated the pushing members 42,. 43, 46, 46w, Wl'll be moved lengthwise 1n the recess 24.-, V v Each pushing member is provided at opposite ends thereof'withthe projections 47, the projections 47 at one end, having inclined f-ace'sr Between the two sets of pushing and disposed in the recess .24 are two'sets ofjiarcu'ate plates 48 and 49 connected by arbors 50 extending through the opposite ends of a. plurality ofconnector plates 51, and between these connector plates and surrounding the arbors rollers 52. f

When the curved plates 48, 49 with their connector platesj51 and rollers 52 surround- 50-are a plurality of ing the arbors: 50. are disposed in the recess,

the outer end rollers '52 will bear against projections 47 upon the pushing members 42 and 4600, while the inner end rollers will bear against similar projections 47 upon the pushing members 43 and 46.

The split rings and 26 have projecting tracks 53', 54, formed thereon on which the rollers 52. are adapted to rotate about the arbors 50. I

The normal position of the connector menu bers 51 are as shown in 5, and when in th s positlon the. drum15 is'f-ree to revolve relatively to the split rings 25 and 26.

i As soon,however, as the'cams29, 31 are rotated to actuate thepushing members 42,

43. 46, 46%, the various connector members will be moved intoa'position more nearly,

radial to" the axis of theshaft'lO, and cause thesplit rings 25,".26, to be separated and forced into frictional-contact withthe cy-- so that the lindrical walls of the recess 24 drum 15 will'be locked to said rings 25' and hen members i the rings 25, 26, are impinging upon the walls of the recess 24 n this-manner, the

"of the shanks and 32 and while the clamp nuts arefree fromcontact with the levers 33 the cam members 29, 31 are moved simultaneously into their normal positionsand then-the clamp nuts 35 are moved against said levers 33 to lock them to the threaded shanks 30 and 32.

By the use of the toolboth cam members therefore are atthesame time brought into exactly the same position relatively to the pushing members 42 43, 46 and 46% with which said team members 29, 31 coact.

When the pushing members 42, 43 are moved in opposite directions by the cam member29 thefiat endedprojections 47 of'one member 42 will come into contact with the rollers 52 at-the end of the outer arcuate plates 49 and force said arcuate plates in one direction whilethe arcuate plates 48 are being forced in the opposite direction by the flat-ended proiections'47 contacting with the rollers 52 at the'end of the said plates 48.

At the same time the movement of cam member 31 will cause the pushing members. 46. 46:2? to move in opposite directions against rollers 52 at the opposite ends of said arouate plates 49, 48.

The combined movement of these pushing members will tend to move the connector plates 51 more nearly radial. and in so doing force the rollers 52 against the bearing faces.

53. 54 ofth-e split rings 25. 26' and cause said rin s 25. 26 to impinge upon the opposite annular walls of the recess 24 so that the members 13, 1.5 will be temporarily locked together. A v b When the cam members 29. 31 are return d to their normal position the spring of the metal] of which the split rings 25. 26 is made will permit said rings to be released from gripping contact with the annular walls of said recess 24.

The inclined fa ces of one set of projections 47 perform no oflice. these proiections being thus formed to provide as much bearing surface as possible between the pushing members 42, 43, 146 and 46m and the split rings with-which they-coact.

The pushing members 42,43 are arcuate and in contact with, one another, the line of contact beingcoincident with the axis of the cam member 29 sot-hat when said cam memher is oscillated the movement in opposite directions. of. these members: is assured.

The memberdQ rides on the inner bearing;

surfaces of the, outer split ring while-the bearing other-Vmember 43 rides on the outer surfaces of the inner -ring26. c.

Similar action takes place with cam member 31 and pushing members 46, 4605.

T he outer ends of arbors. or spindles-5O are upset over the outer faces. of the; arcuate plates: 48, 49, thereby" securing together all the elements of the ring separating mechanism so that each ring separating mechanism may be inserted into or removed from. the reccss 24 as a unit. c Any desired degree of frictional contac between the rings 25-, 26, and the cylindrical walls. of the recess 24, may be obtained by the adjustment of the cone member 37.

It is believed that the operation andmany advantages of the invention will be under-' stood without further description.
